Microprocessor Controls

All Units shall be fitted as standard with the latest Delta range of DIN rail mounted Microprocessor Controls. The Control System utilises a main Microprocessor Interface Board equipped with a set of terminals necessary to connect the Board to the controlled devices (e.g. valves, compressors, fans, reheats, sensors and humidifiers). All software is permanently stored in flash RAM and is therefore protected even in the event of a power failure. Unit software is uploaded to the Microprocessor using a RAM key. On multi unit sites, this quickens unit commissioning. The software can also easily be changed or upgraded on site by qualified service personnel. The Microprocessor also has optional built in Modbus & Bacnet communications and full Windows networking capability. When communicating in Modbus or Bacnet, the protocol converter is in the software & there is no need for external Gateways. The User Interface is complete with LCD Display, keypad and LED Indicators allowing the user to easily set the main control parameters (setpoints, differentials and alarm thresholds) and carry out the main working operations (on/off and displaying controlled variables). The User Interface Terminal also performs the following functions: • Initial programming procedure with access protected by a password. • Possibility of changing the basic operation parameters any time, without stopping the program. • Indication of any alarm condition via audible and visual signals (buzzer sounds and alarm messages appear on the display). • Visualisation of the active functions by means of LED indicators. • Visualisation of the measured variables.

High Efficiency Filters

Higher specification filtration can be provided in addition to the EU4/G4 filters. These filters are of the rigid bag type and have an efficiency of 80% ASHRAE 52/76 (Eurovent EU7/F7). These filters are fitted in the return air side of the unit on a Downflow type and on the supply air side of the unit on an Upflow type.

Fresh Air Kit and Filter

Units can be supplied with a fresh air inlet connection and disposable EU4/G4 filter element. This will admit approximately 3-5% of the recirculated air volume.

Special Colours

Special Colours must be specified when placing orders (quote BS or RAL number or other if known).

Double Skin Panels

To reduce the casing radiated “Break Out Noise”, these panels consist of an inner solid steel sheet. The inner skins are painted and finished in unit colour.

Fire/Smoke Detector

A fire/smoke detector can be mounted in the return air path to interface with the unit controls and generate an alarm.

Firestat

A firestat can be located in the return air path within the unit to interface with the unit controls and indicate an alarm.

Hot Water Reheat

Units may be fitted with a Low Pressure Hot Water (LPHW) heating coil in place of the standard electrical resistance heating. Water flow through the coil is controlled by a 2 or 3 way on/off valve. Duties of these coils are nominally the same as standard electric heating, based on flow and return hot water temperatures of 82o C and 71o C respectively. Upsized Fan Motors

For applications where fan power requirements exceed the capacity of the standard motors, an upsized motor can be fitted. Standard unit ESP is 75 Pa. Units can normally be upgraded to 300 Pa. In these instances please consult the factory.

Water Detection

A Water Sensor Module is connected to the Unit Microprocessor Control System and supplied with 10m of cable for underfloor water detection. When water is detected the unit’s alarm system is activated.

Condensate Pump

Where, due to location, it is not possible to gravity drain units, a condensate pump can be fitted to collect any condensate and pump it to the nearest convenient drain point (pump duty is 6 l/min Vs 6m head). For units fitted with humidifiers or units requiring a lift in excess of 6m equivalent head, a larger capacity sump pump is available, (Pump duty is 6 l/min Vs 10m head).

Top Entry Pipework

The unit pipework can be modified to allow entry/connection of services through the top of the unit.

Reverse Fan Deck

For applications where the air should be discharged “backward” from the unit, the fan deck can be reversed to ease the airflow pattern and reduce pressure drop.

Notes 1. FLA = Full Load Amps. 2. Unit maximum FLA is the total of the components, which operate during maximum electrical load conditions. For full

function units with humidifier & electric reheat the maximum FLA would be in dehumidification mode ie. cooling + reheat or in cooling and humidification mode ie. cooling + humidifier.

3. In dehumidification mode, calculate the max FLA based on single compressor FLA as only one compressor operates in this mode. Tabulated values for compressors above are for two compressors.

4. In cooling and humidification mode, calculate the max FLA based on dual compressor FLA as both compressors and the humidifier operate in this mode.
